Step-by-step solution
Plants require nutrients for proper growth and development. 16 elements are necessary for plants and are called essential elements as C, H, O, N, P, S, K, Mg, Ca, Fe, Cu, B, Zn, Mn, Mo, and Cl. These essential elements are categorized into 2 groups as macroelements and microelements. Macroelements are required by plants in larger amounts e.g., C, H, O, N, S, P, K, Ca, and Mg. Microelements or trace elements are required by plants in very small amounts i.e. in traces e.g., Fe, Cu, B, Mn, Mo, and Cl.
